I would urge to report this issue to AMD GPU driver team through their driver suite Bug report utility. The more of us shout at them the more chance someone will wake up. Not the best behavior from so called project partner. smh
Keep in mind 6900xt gets as low as 2.6m ppd in majority of the projects even with 21.3.2 driver. On the upswing, max I have seen is 4.8m PPD I believe. So adjust that to your 6600xt. nVidia's 3000 series in CUDA mode still miles ahead
nVidia has a man who is co founder of folding@home project, so his dedication to optimize and push performance paid off. AMD's involvement with the project is more shallow. The middle management knows the issue, but it is low priority for them unfortunately. If Lisa Su knew about this, I am sure we would have person or two optimizing things. I ran out of voice and favors by now trying to pull someone from AMD to get involved...MeeLee wrote:I wonder if AMD (Lisa Su) knows how much they're missing out on people folding not buying their GPUs.muziqaz wrote:You need to use 21.3.2 driver for your PPD to be somewhat decent (AMD in general is crap at folding).

Not that it matters, because AMD GPUs always have less shaders than Nvidia of the supposed same category.
It's like a 6600XT should be the same as a 3060, in some games, but Nvidia GPU has double the shaders/cuda cores at only about 20% lower core frequency; resulting in much more efficient folding.
Eh, not quite double, and not 20%. But the bigger difference is in how those cores are structured.MeeLee wrote:Not that it matters, because AMD GPUs always have less shaders than Nvidia of the supposed same category.

I was about to question this, but sure enough the Radeon driver interface does have 'poor performance' listed as an option in the 'report a bug', so...works for me! If AMD considers poor performance a bug, I'm happy to file a bug report about it...muziqaz wrote:so only solution (besides hacking the older drivers): spam all available AMD social media feeds and their bug report utilities with these issues
There is no need to sugar coat their ignorance with poor performance option. They need to be blasted big time for this. Not only have they been completely ignoring f@h optimization wise for year, but they are also ignoring the fact that they dropped performance specifically for f@h by ~50% with their newer drivers.XanderF wrote:I was about to question this, but sure enough the Radeon driver interface does have 'poor performance' listed as an option in the 'report a bug', so...works for me!

I did include links to the folding.lar.systems site for comparison, to show this problem isn't specific to my system, but more broad.
The core frequency of Nvidia GPUs is kind of BS. I have never owned a (modern RTX) Nvidia GPU that couldn't hit 1850Mhz constantly, and 2035Mhz under high boost/overclock.XanderF wrote:Eh, not quite double, and not 20%.

For single-precision calculations, the 6600xt does trail the RTX 3060. OTOH, for half-precision or double-precision calculations, the 6600xt is CONSIDERABLY more capable. Either way, the 3060 raw numbers don't explain how the card is getting triple the PPD of the 6600xt - these cards SHOULD be trading blows, more or less.Code: Select all
